Is this a sign of a malware infection?

I've noticed that both my desktop and laptop (windows 7) have a very similar error message under System logs. Here is an example:

Application popup: Windows - Application Error : The instruction at 0x77752239 referenced memory at 0x00000014. The memory could not be written.

Click on OK to terminate the program

Click to expand...

The instruction can vary but the referenced memory is always 0x00000014. Both computers do this within about 10 minutes from boot. The laptop is a really fresh install and has nothing on it but COMODO, MBAM, Dropbox, Chrome, Sandboxie and Microsoft Office. I've seen this error associated with Adobe but I have no Adobe products on my system.

This has been going on my desktop since early June, when I installed Windows 7 again.

Could this be a result of SEHOP or DEP? Is there a way to see what is at the instruction or at the referenced memory? Or am I just overreacting?

I see this sort of memory error all the time on Google in regards to Adobe Reader, but I don't have Adobe Reader (any version) installed on either PC. It also seems to happen without any user interaction.
